Urology Journal , 2010,
Abstract: PURPOSE: To compare erectile function following low flow priapism in patients undergoing distal and proximal shunts. MATERIALS AND METHODS: From January 1995 to December 2005, we retrospectively studied 16 patients who presented to our medical center with refractory priapism. Of 16 patients, 5 underwent Winter shunt, while El-Ghorab procedure was performed for 7 patients and the remaining 4 underwent Grayhack shunt. Erectile function was assessed in a minimum follow-up of 2 years (range, 2 to 10 years) using erectile dysfunction (ED) intensity scale [Total score: 5 to 10 (severe ED); 11 to 15 (moderate ED); 16 to 20 (mild ED); and 21 to 25 (no ED)]. RESULTS: The mean patients’ age was 40.62 ± 15.27 years. Mean duration of priapism was 51.12 ± 37.99 hours. Of 4 patients (25%) who underwent proximal shunt (Grayhack procedure), 2 (50%) were impotent, 1 had potency, and the other one achieved some penile erection with administration of oral sildenafil. Of 5 patients (31.25%) who underwent Winter procedure, 1 died because of metastatic bladder cancer and of 4 remainders, 2 (50%) had normal erectile function, but 1 patient suffered from recurrent priapism. Of 7 patients (43.75%) who underwent El-Ghorab procedure, 1 was lost for follow-up and of remaining 6 patients, 2 (33.3%) had normal erectile function and 4 (66.6%) were impotent. No surgical complication was seen. Median lag time from priapism till surgery for patients with and without ED was 48 and 26 hours, respectively (P = .22). CONCLUSION: Grayhack shunt is a safe surgical procedure without any major complications and with lower ED rate. Grayhack shunt might be considered as treatment of choice for refractory low flow priapism.

Urology Journal , 2004,
Abstract: Purpose: We reported the outcome and complications of laparoscopic aberrant vessels transposition without performing pyeloplasty in patients with ureteropelvic stenosis. Materials and Methods: A total of 10 patients with ureteropelvic stenosis accompanying with aberrant vessels underwent laparoscopic transposition of vessels between June 2001 and March 2003. 4 of the cases were male and 6 were female, and 4 out of 10 had right side and 6 had left side involvement. The mean age was 31.9 (14 - 59). Reaction of aberrant vessels was performed by cutting the vain and fixing the artery to the lipid layer around the kidney and renal pelvis. Results: The procedure was successful in all the cases without any perioperative complications. The operative time was 2.20 hours (1.45 - 2.50) including cystoscopy, DJ placement, and transposition. Mean hospital stay was 2.9 (2-5) days, and patients were followed up an average of 9.1 (3-22) months. Except one case of rehospitalization due to pain, no complication occurred. The rate of clinical and radiological improvement was 100% and IVP showed a decrease in the degree of hydronephrosis as well as the resolution of obstruction observed in renogram. Conclusion: With regard to our findings, it seems, at least in a proportion of patients with UPJ stenosis accompanied with crossing vessels, that mechanical compression is the mere cause of obstruction and primary stenosis does not coexist. As a result, treatment is achieved by transposition of the crossing vessels without entering the renal unit.

Urology Journal , 2005,
Abstract: Introduction: Since the introduction of percutaneous nephrolithotomy (PNL), many modifications to entering the pyelocalyceal system have been made. One alternative is to insert a needle pointed to an opaque stone as a landmark. The aim of this study was to compare the outcomes of managing kidney calculi by PNL with and without retrograde pyelography. Materials and Methods: In this randomized controlled trial, 55 candidates for PNL with a single opaque kidney calculus in the calyx alone, the pelvis alone, or both the calyx and the pelvis were assigned into 2 groups. Twenty-seven patients underwent PNL with a ureteral catheter, and 28 patients underwent PNL without a ureteral catheter. Clinical outcomes were compared between the 2 groups using plain radiographs taken on the first day after the procedure. Results: Patients had similar distributions regarding sex, age, operative time, hospital stay, past surgical history on the kidneys, and stone size. There was a significantly greater decrease in postoperative hemoglobin level in patients having PNL with a ureteral catheter (P < .001) than in those having the procedure without a ureteral catheter. No differences were seen among patients in the 2 groups in terms of stone-free rate, and number of patients with insignificant residue, and those needing extracorporeal shock wave lithotripsy, a second PNL procedure, or transurethral lithotripsy. Conclusions: Percutaneous nephrolithotomy without ureteral catheterization has specific benefits: urine leakage is lower and there is no need to perform cystoscopy. Patients with a single kidney calculus are good candidates for PNL without previous ureteral catheter insertion.

Urology Journal , 2012,
Abstract: Purpose: To compare two matched groups of men with bladder transitional cell carcinoma (TCC) who underwent prostate-sparing cystectomy (PSC) or conventional radical cystoprostatectomy (CRC).Materials and Methods: Twenty-three men who have undergone PSC with the diagnosis of bladder TCC (Ta–T2) from 2003 to 2008 in Tehran, Iran were included in the study as the experimental group. The control group composed of 27 men with comparable tumor characteristics and age range, who had non-nerve-sparing radical cystoprostatectomy and orthotopic ileal W pouch reconstruction in the same centers. All the procedures were performed by the same surgical group under the supervision of different attending staff.Results: Mean follow-up period was 39 months in PSC and 35 months in CRC group. The 5-year overall survival was 47% and 30% in PSC and CRC groups, respectively. Median survival was 48 months in PSC and 36 months in CRC group, using Kaplan-Meier survival analysis (P> .05). Impotence was observed in 16.6% in PSC and in 83.3% in CRC group (P = .002). Mean International Index of Erectile Function-5 score of the PSC group was 19.8 compared with 5.7 in the CRC group (P = .003). Only one patient in each group was completely incontinent. Urethral anastomosis stricture occurred in 2 patients in CRC group.Conclusion: Patients who underwent PSC did not show decreased overall survival compared to CRC, which provided better functional results.

Abstract: Purpose: To compare clinical and radiological outcomes, complications, and hospital stay in laparoscopic and open pyeloplasty. Materials and Methods: From February 2002 to February 2003, 69 patients with ureteropelvic junction obstruction (UPJO) were assigned into two groups. Thirty-seven patients underwent transperitoneal laparoscopic pyeloplasty and 32 underwent open surgical pyeloplasty. Clinical symptoms were assessed before and after surgery, subjectively. Radiological assessment was also done three months postoperatively. Results: Mean operative time was 3.2 hours and 2.2 hours in laparoscopic and open pyeloplasty groups, respectively. Intraoperative bleeding was trivial in both groups and no complication or conversion to open surgery occurred. Postoperative complication rates were 24% and 6% in laparoscopic and open pyeloplasty groups, respectively. Mean hospital stay was similar (6.2 days) in the two groups. Mean follow-up was 16.5 months versus 11.4 months. Clinical and radiological success rates were 89% and 83.8% for laparoscopy group versus 96.5% and 87% for open pyeloplasty group. Due to recurrence of stricture, repeated surgery was performed in 4 patients of laparoscopy and 1 of open pyeloplasty groups.Conclusion: Laparoscopic pyeloplasty is a less invasive method with less pain, cosmetic advantages, no long incision, and outcome comparable with open surgery. Hospital stay is also not longer than that in open surgeries. Hence, laparoscopic pyeloplasty can be a substitute for skilled surgeons.

Urology Journal , 2006,
Abstract: Introduction: The aim of this prospective study is to determine the relationship between the pathologic characteristics of the transitional cell carcinoma (TCC) of the bladder and prostatic involvement. Materials and Methods: Sixty men with bladder TCC underwent standard radical cystoprostatectomy and were enrolled in this study. Vascular and perineural invasion, maximum diameter of the tumor, presence of carcinoma in situ, distance between the tumor and the bladder neck, and grade and local stage of the tumor were recorded and their relation with prostatic involvement was studied. In addition, hydronephrosis and age of the patients were included in the analysis. Results: The mean age of the patients was 63.9 ± 11.1 years. Of 60 men included in this study, 15 patients were found to have prostatic involvement with TCC (25%). Univariate statistical analyses showed that vascular invasion and the distance between the tumor and the bladder neck were significantly related to the prostatic involvement (P = .007; P < .001). But, in the logistic regression, only the distance between the tumor and the bladder neck was significantly related to the prostatic involvement (P = .001). Conclusion: This study suggests that the probability of prostatic involvement in patients with bladder TCC tumors near the bladder neck is high. Prostate-sparing or capsule-sparing cystectomy should be avoided in such patients.

Urology Journal , 2009,
Abstract: Introduction: We reviewed urinary outcomes after sutureless vesicourethral alignment in open radical prostatectomy (ORP) and laparoscopic radical prostatectomy (LRP). Materials and Methods: Charts of 324 patients who underwent sutureless ORP (n = 188) and LRP (n = 136) were reviewed. After prostatectomy, a 22- to 24-F silicon Foley catheter was passed into the bladder via the preserved bladder neck. The Foley balloon was filled, and mild traction was applied to appose the bladder neck to the urethral stump. The Foley catheter was fixed to the patient's leg. No cystostomy was placed. Results: The follow-up period ranged from 12 to 60 months. The mean operative time was 65 minutes in ORP and 260 minutes in LRP. Blood transfusion was significantly less frequent with LRP (9.6% versus 19.7%, P = .02). The mean postoperative catheterization durations were 12 days in ORP and 13 days in LRP. Complete continence was achieve in 293 patients (90.4%) after 3 months of follow-up (88.9% in LRP and 91.5% in ORP, P = .78). The continence rate improved to 96.3% in LRP and 95.2% in ORP at 1 year (P = .52). Bladder neck stricture rate was 13.6% (12.8% in ORP versus 14.7% in LRP, P = .87). Conclusion: Sutureless vesicourethral alignment during ORP and LRP is a promising approach with minimum urinary extravasation, a high rate of continence, and an acceptable rate of stricture. This technique could be considered as an alternative in anatomically demanding situations.

Abstract: PURPOSE: To evaluate the predictive factors for prostatic involvement according to the bladder transitional cell carcinoma (TCC) characteristics in a prospective study.MATERIALS AND METHODS: Hundred patients with the bladder TCC who had undergone standard radical cystoprostatectomy were enrolled in this study. A number of factors, including vascular and perineural invasion, number of tumors, maximum diameter of the tumor, presence of carcinoma in situ, distance between the tumor and the bladder neck, grade, and local stage of the tumor were recorded, and their elationships with prostatic involvement were studied. In addition, hydronephrosis and age of the patients wereincluded in the analysis.RESULTS: The mean age of the patients was 62.6 ± 10.8 years. Of a total of 100 patients, 21 (75%) were found to have prostatic involvement with TCC. Univariate statistical analysis showed that vascular invasion and the distance between the tumor and the bladder neck were significantly related to the prostatic involvement (P = .001 and P < .001) and tumor stage had relatively low P value (P = .08). In the logistic regression, only the distance betweenthe tumor and the bladder neck was found to be significantly related to the prostatic involvement (P = .004).CONCLUSION: This study demonstrated that distance between the tumor and the bladder neck is a predictive factor for prostatic involvement; hence, prostate-sparing or capsule-sparing cystectomy in patients with tumors in short distances from prostatovesical junction is not rationale and should be avoided.

Urology Journal , 2007,
Abstract: Introduction: The aim of this study was to determine the correlation between histological subtype, size, grade, and stage of the kidney tumors and to investigate whether a correlation exists between the size of the kidney tumor and its behavior. Materials and Methods: Between 1996 and 2004, we had 212 patients with radical or partial nephrectomy due to a kidney tumor at Shaheed Labbafinejad Medical Center. Their pathologic blocks were re-evaluated with consideration of their tumor size and pathologic features. Results: Of 212 pathologic blocks, 17 (8%) were benign and 195 (92%) were malignant masses including 179 renal cell carcinoma (RCC) tumors. Malignant tumors were slightly greater compared with the benign ones (P = .10). There was no significant relation between the size of tumor and the histological subtype. Significant relations between the size of the kidney tumor and the nuclear grade (P = .007), clinical symptoms (P = .02), and extracapsular extension (P < .001) were observed. In smaller RCC tumors (< 4 cm), extracapsular extension (stages T3 and T4) was rare (1 in 29). However, smaller RCC tumors were not significantly different from those larger than 4 cm regarding the nuclear grade, symptoms, and histological subtypes. Conclusions: Tumor size is not an independent predictor for the histological subtype of the tumors; however, larger malignant tumors may have higher grades, higher stages, and clinical symptoms.
